Sam and Dean battle a Shtriga, a witch that sneaks into childrens' bedrooms and sucks the lives out of them. Dean must relive his childhood when he remembers that he encountered the Shtriga years ago.

In this Christmas-themed episode, Sam and Dean follow the trail of a creature that abducts its victims by using their chimneys. Dean would like to celebrate Christmas like they used to when they were children, but Sam isn't exactly feeling the Christmas spirit.
